Fresh

Aldehydes smell like a crisp, almost electric freshness—imagine the sharp, waxy brightness of a newly opened bar of soap, or that clean snap you get when you peel the white pith from inside a lemon skin. There's a slightly soapy, almost metallic quality that's oddly luxurious and powdery. They're not quite fruity or citrus themselves, but rather the *idea* of cleanliness—the scent of polished surfaces and starched linen. Some find them slightly peppery or even a touch metallic, like touching a cool stainless steel sink on a bright morning.

Floral

Rose smells like romance bottled. Imagine walking through a garden after rain—that's the green, slightly damp quality. Then there's the sweetness: honeyed, sometimes with a whisper of spice and subtle fruit notes. Depending on the variety, you might detect hints of honey, jam, or even a peppery warmth. It's never cloying if it's genuine; there's an elegant complexity, a velvety depth that makes you want to inhale again.
